Overview
GeForce GT 650M v2 SLI is a solution of two GeForce GT 650M v2 put together using NVIDIA's SLI technology.

Architecture
The Kepler Architecture was NVIDIA's big step to power efficiency. Each Stream Multiprocessor (SMX) now hosts 192 Shader Processing Units - against the 48 of older Fermi Architecture, and has been redesigned being now clocked at the same speed of the Central Unit. This means they are more energy efficient and will consequently lead to cooler operating temperatures. However, it also means they are weaker. It can be said that one Fermi SMX is as fast as 2 Kepler SMXs.
Additionally, and not available in all GPUs, Kepler also introduced the Boost Clock Feature. The Boost Clock is an even higher Clock Speed activated when in gaming mode and becomes the effective speed of the GPU.

GPU
It consists of 2 GPUs codenamed GK107 which, together, offer 768 Shader Processing Units, 64 TMUs and 32 ROPs, on a 256-bit memory interface of fast GDDR5. The central unit runs at 745MHz, while the memory clock operates at 1753MHz.

Power Consumption
Power Consumption lies between 85W and 95W. As a result, this combination may only be used in very large laptops.

Performance
Gaming benchmarks prove that GeForce GT 650M v2 SLI is overall as fast as a single GeForce GTX 670MX.

System Suggestions
We recommend a strong processor (Intel Core i7) and 8GB of RAM for a system with GeForce GT 650M v2 SLI.
